Imperial Malt Emerald

From the Latin imperialis, of the empire — applied to color since the medieval period for the hues reserved for sovereigns and empires: imperial purple of Tyrian dye, imperial yellow of Ming-dynasty porcelain. As a modifier, imperial implies saturation combined with the institutional weight of a color owned by a court. Sits in the bold-and-deep corner, alongside royal.

Old English mealt, germinated-grain. As a color modifier, malt implies a kilned-grain-and-amber-stout quality, the visual register of Burton-on-Trent-and-Bavarian-malt hand-kilned-grain-and-amber-stout Burton-on-Trent-and-Bavarian-malt-and-Munich-and-Pilsen malt-and-kilned-grain surfaces under Burton-on-Trent-and-Bavarian-malt-and-Munich-and-Pilsen Burton-and-Munich-and-Pilsen brewery-and-kiln-light. Sits at the modifier-and-flavor end of the grid, parallel to syrup and zest in usage.

A chromium-tinged variety of beryl — the gemstone mined from the Cleopatra-era Mons Smaragdus in Egypt, the Muzo deposits of Colombia, and the Sandawana mines of Zimbabwe. Emerald green refers to a high-clarity faceted emerald with strong color saturation: a saturated, slightly blue-shifted green with the gem's signature internal life. Cooler than fern, warmer than teal, with the heraldic weight of two thousand years of royal favor.
